Description
The SKY13441 is a Single Pole, Ten-Throw (SP10T) antenna
switch with an integrated General Purpose Input/Output (GPIO)
interface and dual low-pass harmonic filters. The switch has eight
transmit/receive ports, any of which can be used for WCDMA
transmit/receive or GSM receive functions.
Using advance switching technologies, the SKY13441 maintains
low insertion loss and high isolation for both transmit and receive
switching paths. The switch also exhibits an excellent triple beat
ratio and 2
nd
/3
rd
order modulation distortion performance.
Figure 1. SKY13441 Block Diagram
Switching is controlled by an integrated GPIO interface. Depending
on the logic applied to the decoder, the antenna pin is connected
to one of ten switched RF ports using a low insertion loss path,
while the paths between the antenna pin and the other RF pins are
in a high isolation state. No external DC blocking capacitors are
required on the RF paths.
The SKY13441
is
manufactured in a compact, 3.2 x 2.5 mm,
20-pin
Multi-Chip Module (MCM) package.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION:
Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13441 are provided in
Table 2. Electrical specifications are provided in Table 3. Table 4
provides the control logic for the SKY13441.
Typical performance characteristics of the SKY13441 are
illustrated in Figures 3 to 13.
The isolation matrices shown in Tables 5 and 6 provide the port-
to-port
isolation and the antenna-to-port isolation for all available
RF states at four different frequencies: 915, 1910, 2170, and
2690 MHz.
The insertion loss matrix shown in Table 7 provides the insertion
loss for all available RF states at eight different frequencies: 704,
824, 915, 960, 1710, 1910, 2170, and 2690 MHz.
Figure 14 illustrates the test setup used to measure data for
Figure 11. This industry standardized test is used to simulate the
WCDMA Band 1 linearity of the antenna switch. A +20 dBm
Continuous Wave (CW) signal, f
FUND
, is sequentially applied to the
TRX1 through TRX8 ports, while a
–15
dBm CW blocker signal,
f
BLK
, is applied to the ANT port.
The resulting 3
rd
Order Intermodulation Distortion (IMD3), f
RX
, is
measured over all phases of f
FUND
. The SKY13441 exhibits
exceptional performance for all TRX ports.
